US President Donald Trump and First Lady Melania Trump, welcomed King Charles and Queen Camilla to the White House on Monday (27 April). The two couples greeted each other outside by the historic building’s south portico overlooking the lawns where past presidents have hosted Queen Elizabeth II. Queen Camilla gave a special nod to the US-UK relationship, wearing a brooch featuring the American stars and stripes crossed with the Union flag. The brooch was presented to Queen Elizabeth II during her 1957 state visit to America on behalf of New York during a civic lunch hosted by the city’s then mayor, Robert F Wagner. The visit is the most important foreign trip of the King’s reign so far as it comes during a pivotal moment for the UK and US, with relations between the Prime Minister and US President Donald Trump fractious.
